I've gone on several customer visits over the years to give training seminars, marketing pitches, and troubleshoot PCBs in their various labs. Some of the standouts include well known semiconductor fabs on the West Coast, high profile consumer companies in Korea and Israel, plus some automotive clients in the Rust Belt.

Israel definitely stands out as the coolest place hands down. I'd go back in a heart beat. Eating lunch in Jaffa, sitting on the Mediterranean, during an off day is burned into my mind.
